Players fought on the court. Police intervened. Another player fought the police. The teams combined for 107 fouls. Twelve players committed enough fouls to foul out, but some got to stay on the court anyway so there’d be enough to each side. Two players reached seven fouls. Bob Cousy scored 50 points, shooting 30-of-32 on free throws. The Boston Celtics eliminated the Syracuse Nationals with a 111-105 quadruple-overtime win in Game 2 of the 1953 Eastern Division semifinals.

And thus concluded the first playoff series between the longtime franchises.

The Celtics and 76ers, who moved to Philadelphia from Syracuse and changed their name, will meet again in the postseason tonight. The second-round series will be the record 20th playoff-series matchup between the franchises.

It also could be just the start of a renewed rivalry.

LeBron James has run the Eastern Conference for the better part of a decade with the Heat and Cavaliers, but his control appears to be slipping. Boston and Philadelphia look ready to take the throne, both teams set up to compete with each other for a long time.

The 76ers are led by 24-year-old Joel Embiid and 21-year-old Ben Simmons. They have an impressive and well-fitting supporting cast, and – especially 24-year-old Dario Saric – some of those secondary players are also still young. Philadelphia also has enough cap space to add another impact player this summer – maybe even LeBron.

And both teams have extra draft picks, some very valuable. (The Celtics acquired one from the 76ers, who traded up to draft Markelle Fultz No. 1 last year.)

This arms race started years ago in both Boston and Philadelphia.

Celtics president Danny Ainge traded Kevin Garnett and Paul Pierce to the Nets while those two were still leading teams to the playoffs and got a boatload of picks. Ainge kept flipping veterans – Rajon Rondo, Jeff Green and even Coach Doc Rivers for more draft picks.

Sam Hinkie’s Process gave Philadelphia a wealth of assets. Not only did they tank their way to several high picks (drafting Embiid and Simmons), the 76ers cleverly extracted extra selections from win-now teams looking to shed salary.

Now, Philadelphia is ready to win and still, like Boston, has extra picks still coming (unlike the Raptors, who had the East’s best record this season but also have older stars and are out this year’s first-rounder). The 76ers and Celtics can use those extra picks to infuse their teams with young talent or trade them for immediate upgrades. The luxury is in the choice.

This won’t be the marquee matchup that awaits in years to come. Irving and Hayward (and Daniel Theis) are out for Boston. Philadelphia is the big favorite.

But even in a rivalry more than six decades old, this feels like just the start of something.

There are multiple reasons the Toronto Raptors have beaten the Milwaukee Bucks three times in a row and now are one win away from the franchise’s first trip to the NBA Finals.

Kawhi Leonard and his play — particularly his defense on Giannis Antetokounmpo — is a huge one. So is the Raptors incredible halfcourt defense, which has held the Bucks to an 84.3 net rating on halfcourt possessions in this series. When the Raptors have been able to slow the game down (which they have done very well the last two games, with possession totals in the mid-90s) they win.

Just don’t forget about the Raptors bench.

Fred VanVleet, Serge Ibaka, and Norman Powell — the three guys coach Nick Nurse leans on in his regular rotations — have been critical for the Raptors, and if they are again on Saturday night in Toronto it will lift the franchise to a place it has never been before.

In Game 5, it was the Raptors’ bench that led the comeback after the Bucks’ fast start. It has been that way all series. Lineups that have at least one of those core three Raptors bench guys on the floor are +30 this series. Lineups with all three of them on the court together are +12.

Different guys are stepping up each game. In Game 5 it was VanVleet’s turn. After a rough few games in this series, he got to Milwaukee late after being with his wife for the birth of their son, then proceeded to knock down 7-of-9 threes in Toronto’s come-from-behind win.

“He oozes the confidence that spreads to the other guys,” Toronto coach Nick Nurse said of VanVleet. “Again, he just stepped into the shots that were there tonight, and he was probably due to get hot in these playoffs. It’s been probably a long time coming. Great game by him.”

Toronto’s bench — and Leonard — are key reasons that this team responded to adversity, going down 0-2 in the series and bouncing back. It’s the experience of having been there before, having dealt with the pressure before, learning about themselves because they have been tested like this in previous years. Leonard and Green have rings from San Antonio, Gasol has been to conference finals in Memphis, Lowry has been there through all the Raptors struggles in recent playoffs. On the bench, Ibaka has seen plenty, and these guys have not been fazed by the moment.

It’s the test the Bucks are facing now — this group had never been challenged like this. Their athleticism and Antetokounmpo’s MVP-level season propelled this team to the best record in the NBA, then they swept through the first two rounds of the playoffs with an 8-1 record. After that, they beat the Raptors the first two games of this series.

However, now they have lost three in a row for the first time all season and they are learning about their weaknesses. The Bucks entire offense is based around the idea that nobody can slow Antetokounmpo one-on-one, except that Leonard has done just that. The Greek Freak has shot 35.5 percent this series (11-of-31, via Second Spectrum data) when Leonard has been his primary defender. Antetokounmpo also hasn’t found shooters and those guys have not hit the passes he does make, particularly in the halfcourt. Toronto has controlled the tempo the past few games, and when Antetokounmpo isn’t getting easy buckets in transition the Milwaukee offense stumbles. Toronto also has taken care of the ball and hit shots, with Leonard getting to his spots on the floor, which has limited the Bucks transition chances.

The Bucks need to make adjustments — finding ways to get Antetokounmpo the ball with better matchups, not having him attack from the top of the key every time and giving him some picks to force switches — and they need another ball handler, such as Eric Bledsoe or George Hill, to have a monster game. Khris Middleton and Malcolm Brogdon can and should do a little more shot creation.

And Milwaukee has to contain that Raptors bench and not get beat so badly when they are on the floor.

If not, the Bucks will be on vacation in Cabo next week while the Raptors are still playing.

After a slow start to the season, by the end the Houston Rockets had found their groove and were the second best team in the West. That still wasn’t good enough to get by the Warriors dynasty. That has led to some soul searching in Houston.

And some changes to the assistant coaching staff. First came the news Jeff Bzdelik would not return in his defensive coordinator role. Then on Friday, Jonathan Feigen of the Houston Chronicle put out a series of Tweets talking about the other coaching changes coming.

Cho had been with the Rockets for a decade. Roland worked closely with James Harden, among others.

This is a near total overhaul of Mike D’Antoni’s staff, which has led to speculation the Rockets are trying to push their coach out the door, reports Marc Stein of the New York Times.

New owner Tilman Fertitta told @Jonathan_Feigen earlier this month he intends to keep Mike D'Antoni as Houston's coach, but the flurry of changes imposed on D'Antoni's staff has some in the coaching community wondering if the Rockets are trying to nudge D'Antoni toward the exit https://t.co/aeTgeUpkHx

D'Antoni, for his part, has said in numerous interviews that he remains hopeful of securing a multi-year extension from the Rockets after a three-season run in which Houston has been widely regarded as the league's second-best team. MDA has only one season left on his contract

D’Antoni has done an excellent job — and adapted his style — to coach these Rockets into being contenders. He is part of the reason this franchise is a contender. The Rockets have fallen short the last two seasons not because of D’Antoni, but rather because of the Warriors. Golden State is an all-time dynasty level team, they are beating everybody.

This feels like the East in recent years when coaches lost jobs and teams were broken up because they could not get past LeBron James‘ teams when the issue was really LeBron is one of the game’s all-time greats.

There could be other dynamics at play in Houston, but the challenge there is not the coach. If Tilman Fertitta is frustrated his team fell short again, he should start by looking in the mirror at the cost-cutting moves his team made this season to get under the tax line. That put a ceiling on this team more than anything D’Antoni did.

I’d like to think this means we’ll all be able to go to bed at a reasonable hour on June 30. I also know better.

There is a frenzy of activity right as free agency opens (Tampering? There is no tampering in the NBA…), which traditionally has been as the clock turns to July 1 in New York, right at midnight. Things got so active that a lot of agents and players made sure they were in Los Angeles, even if they didn’t live there in the offseason, just so things started at the more reasonable hour of 9 p.m.

Now the NBA has made the rumors official: Free agency will begin at 6 p.m. Eastern on June 30. Six hours earlier than before.

This was done as an agreement between the NBA and the National Basketball Players Association.

This is going to be a wild July with a lot of big-name free agents — Kevin Durant, Kyrie Irving, Klay Thompson, Jimmy Butler — and maybe a third of the players in the league on the market, plus there are a lot more teams with cap space to spend this season. It’s going to be a frenzy.

Every NBA player gets ripped on social media, even the guys who are not on social media. Most of the time players just ignore it, the way they ignore fans yelling stuff courtside or distant family asking them for money.

“Because I have social media,” Durant said Friday… “I mean, I’m a human being with a social media account. I could see if I ventured off into like politics, culinary arts or music and gave my input, but I’m sticking to something that I know. You know what I’m saying? This is all I know. I’m actually talking about stuff that I know. I’m qualified to talk about basketball.

“So when I respond to something, especially if it’s about me personally, of course I’m going to tell you if you wrong about it. When I’m on the training table getting treatment on my calf and I see a tweet that come by and I disagree — I don’t talk to people because I’m worried about what they say, it’s just that I’m interested. So if you talking about in-game or the NBA Finals, they’re the same to me, you know what I’m saying?”

Why does Kevin Durant use social media to join the conversation about himself? “I’m qualified.” His full answer. pic.twitter.com/xFPntIrw4t
